This paper examines change in perceived HIV/AIDS infection risk among youth in Cape Town, South Africa. Data come from waves 1, 3 and 4 of the Cape Area Panel Study (CAPS), a longitudinal representative sample of youth in Cape Town. We test two predictions:
1) Youth who are sexually experienced will have greater perceived HIV/AIDS risk.
2) Youth who know someone with HIV/AIDS will have greater perceived HIV/AIDS risk.
Using generalized estimating equations (GEE) and ordinal logit regression, we find that being sexually active or knowing somebody with HIV/AIDS both result in increased perceived risk of HIV infection in Cape Town. Furthermore, entry into those states – either first sexual activity or first knowing somebody with HIV/AIDS – is associated with greatest increased perceived risk over time. The results suggest that risk behaviors and social networks both influence perceived HIV/AIDS risk.
